Specification of Letters Patent.

Patented Dec. 29, 1914:.

Application filed December24, 1918. Serial No. 808,611.

To all whom it may concern:

Be it .known that 1, Emma WHITMAN RICE, a"""t:itizen of theoUnited States, and a resident ofYonkers, in the county of \Vestchester and State of New York, have invented a new and Improved Book-Marker, of which the following is a full, clear, and exact description. p

My invention relates to improvements in book markers.

The object thereof is to provide a convenient, simple and inexpensive device which will not injure or mar the pages of a book, which Will not obstruct the reading matter of the page when there is substantially no margin, which marker is pro vided with'an identification sign so positioned that the same cannot be soiled or destroyed accidentally, which marker will not disengage itself from the page unless removed, and which marker is provided with means for indicating how far the same should be engaged on the page.

I attain the above object by providing a pair of transparent members interconnected at one end, with resilient means forcing the other ends together, an indicating sign associated with said members at the connecting ends and positioned therebetween, and m ams provided in one of said members adjacent the connected end thereof for indicating how far said members should engage the page.

The invention consists of the construction and combination of parts to be more fully described hereinafter and fully set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which like characters lndicate corresponding parts in all the views and in which:

Figure 1 is a perspective view of a book, some of the pages of which carry an embodiment of my invention; Fig. 2 is a plan View of the marker showing the same in engagement with a page; Fig. dis a section on line 33, Fig. 2; and Fig. 4 IS a section on line 4'-i, Fig. 2.

Referring to the drawings, 5 and 6 represent two rectangular superposed plates or members of transparent material, preferably celluloid. The two plates are interconnected at one end by means of a spacing member 7, which is coated with cement before the same is placed between the plates;

the indicating sign more prominent. The

opposite ends of the said superposed plates 5 and 6 are free from each other, and the free end of the plate 6 extends beyond the free end of the plate 5, so as to facilitate the engagement of a page between the said p ates.

The superposed plates 5 and 6 adjacent the member 7 are provided with a central opening 8 which accommodates the connected ends 9 of the members 10, forming to gether a resilient member engaging the two plates 5 and 6 and tending to bring their free ends together. The plate 5, which is intended to form the upper part of the device, adjacent the opening 8, is provided with notches 11 at theedges thereof. which form an indicator to show how far the said plates should be forced .on to a page. It is understood that, if desired, similar notches 11 can also be provided in the lower plate 6, thus forming an indicator from both sides of the book marker.

From the above it will be seen that the indicating sign provided on the member 7, connecting the two ends of the plates 5 and .6, while perfectly visible through the plates 5 and 6; at the same time is prevented from accidental injury or from being soiled, by the said plates. A perfect engagement between the page and the plates 5 and G is obtained by means of the resilient member formed by the members 10, and any reading matter which may come under the said plates, can be read without in any way disturbing the position of the book marker.

The advantage of my device will be particularly appreciated for use with books having pages made of thin rice paper. which are easily deteriorated and marred by the ordinary marker and on which pages the marking device must be prevented from accidental movement thereon as it will injure the page, that is, the grip of the plates on the page must be positive so as to prevent any displacement thereon. which I obtain by the provision of the spring forcing the free ends of the book marker into engagement with the page, as previously described. 7

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1'. In a book marker, a pair of transpare ent superposed plates; a spacing member rigidly connecting said plates at oneend, 10 said member having an identification sign visible through said plates; and a. resilient member engaging said plates and adapted to force the opposite, nonconnected ends together. 2.

superposed plates; a member between said plates adjacent one end thereof cemented to said plates at the said ends,said members having identification means visible through said 30 plates; a resilient member engaging sai plates and adapted to force the free ends of said plates toward each other. 7

3. In a book marker, a pair of transparent superposed plates connected at one end; and a resilientinember engaging said plates and tending to force the opposite ends of said plates toward each other.

4. In a book marker, a pair of transparent superposed plates; :1 member connecting said plates at one end, said meinber be ing positioned intermediate said platesand having indicating means thereon visible through said plates; a resilient member en- In a book marker, a pair of transparent gaging each of said plates and tending to more the free ends of said plates towar each other, one of said plates having means intended to register with the edge of a page when said plates engage the same.

5. In a book marker, a pair of transparent superposed plates; ing one end of said plates, said member being positioned between said plates and having indicating means visible'throngh said said plates hav ng an aperture adplates, jace'nt' said member; and afresilient member mounted in said aperture and engaging each of said plates so that the free ends of the same are forced toward each other, one

a member connect of said plates having notches adjacent the connected end adapted to register withthe edge of the page when the said plates are made to engage the page.

6. In a book marker, a pair of transparent superposed plates, a spacing member intermediate said plates adjacent one end connecting said plates together, and a resilient member engaging said platesand forcing the free end of said plates toward each other. i

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
